We use a variety of your labels to create almost all of our product line labels. We print them in-house to the sheets with our Xerox printer. We chose to mostly go with black and white to keep things simple and pure. You can see more of the labels on our website
Sheetfed through our Xerox Colorqube 8900 printer.
It is great that you also provide the templates. I found that using those to align things makes it so much easier. I build the labels with Adobe InDesign and use the template as a background layer that I can turn on and off as needed when printing.
